I have found in practice that the capacity for copying by this improved apparatus is practically unlimited having produced as high as two hundred perfect impressions at one time.

Another advantage in the use of my improved roller is that when the operator has moistened a page in the letter-book by run ning the roller out to the edge of the page the leaf will adhere to the roller, so that it can be carried over and deposited upon the page of copy, thus obviating the necessity of handling the page of the letter-book with the fingers-a very troublesome and tedious operation. Thus it will be seen that by my improvement the process of copying letters is rendered very much more expeditious than in the ordinary manner, and the necessity of great care in the manipulation of the apparatus is entirely done away with, and the perfection of the impressions is insured.

Having thus described my invention, What I claim is 1. A moisteningroller consisting of a cylindrica-l receptacle for Water, the same being perforated to permit the escape of the water and provided with a suitable distributingcover located upon the outside of the cylinder, an intermediate retaining-cover located between the cylinder'and the distributingcover, and in connection therewith a suitable filler located atone end of the cylinder, whereby the moistening-liquid may be replenished, and an operating-handle, whereby the device is adapted for use in moistening the sheets of press-copy books, substantially as described.

2. A moistening-roller consisting of a cylindrical receptacle for water, the same being provided upon its exterior with a suitable distributing-cover and being perforated to permit the escape of the moistening-liquid, and provided upon its interior with one or more partitions, the same being perforated to permit the passage of water from one compartment to the other, substantially as de scribed.
